This is a single-zone ductless mini split system for cooling and heating one room without ductwork. It's built for homeowners who want a ceiling cassette indoor head — rather than a wall-mounted unit — for a garage, office, or living space where a discreet, drop-ceiling installation is preferred.
The Air-Con Sky Pro 9000 BTU system pairs the ASLCI4H4S09 outdoor condenser with the ASLEC4H4S09 indoor ceiling cassette, an AHRI-certified matched combination rated at 22 SEER. The 4-way cassette design distributes airflow across a drop ceiling rather than fitting into a joist bay like a slim one-way cassette. Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
System Components
- Outdoor Condenser: ASLCI4H4S09 (9,000 BTU/h, 208-230V, matched to the indoor unit below per AHRI certification)
- Indoor Head: ASLEC4H4S09 — Traditional 4-Way Ceiling Cassette, 9,000 BTU/h, 208-230V
Installation Requirements & Accessories
- Voltage: 208-230V single-phase — confirm this system is being wired to a dedicated 208/230V circuit, not a 115V-only circuit
- Refrigerant line set is sold separately — size is [NEEDS VERIFICATION] in manufacturer data provided; confirm with installation manual before purchase
- Professional installation is required for this system; it is not sold as a pre-charged, no-vacuum DIY kit
- Not compatible with 115V-only circuits
- Not a listed match for ASLEC4H4S12, ASLEC4H4S18, ASLEC4H4S24, or ASLEC4H4S36 indoor heads — each of those pairs with its own correspondingly sized outdoor unit (ASLCI4H4S12/18/24/36)
- Wall/ceiling mounting hardware beyond the standard cassette frame kit is not included
Pro-Installer Tip
On cassette installations, flare connections at the indoor unit are harder to torque correctly than on a wall-mount head because of restricted overhead clearance in the ceiling cavity. An under-torqued or over-torqued flare nut here is a common source of slow refrigerant leaks that show up months later as reduced cooling capacity or an "E1" communication/protection code at the indoor head. Use a digital torque wrench to hit the manufacturer's specified flare torque, and pull the system down below 500 microns with a calibrated micron gauge before opening the service valves. This isn't optional — EPA Section 608 certification is required to handle refrigerant on this system, and a proper vacuum is what protects the 22 SEER efficiency rating you're paying for.
Key Benefits
- 22 SEER rated efficiency on the matched ASLCI4H4S09/ASLEC4H4S09 combination
- 4-way ceiling cassette distributes conditioned air in multiple directions from a single drop-ceiling location
- 208-230V single-phase power supply
- AHRI-certified matched indoor/outdoor pairing

Compatibility & Fitment
- ASLCI4H4S09 outdoor condenser is AHRI-matched to the ASLEC4H4S09 indoor ceiling cassette — this listing covers that specific pairing only
- Compatible with dedicated 208/230V single-phase circuits
- Not compatible with 115V-only circuits
- Not a listed match for ASLEC4H4S12, ASLEC4H4S18, ASLEC4H4S24, or ASLEC4H4S36 indoor heads — those require their own respective outdoor units (ASLCI4H4S12/18/24/36)
- Refrigerant line set is not included and must be purchased separately
- Cassette frame and grille kit ship with the indoor unit; additional ceiling trim/finishing hardware beyond the standard kit is not included
FAQ
What breaker size do I need for this system?
The manufacturer data confirms a 208-230V power supply for this system, but the exact breaker amperage is [NEEDS VERIFICATION]. Check the nameplate on the outdoor unit or the installation manual for the exact circuit requirement before wiring.
Is professional installation required to keep the warranty valid, or is this a true DIY kit?
This is a non-DIY, standard flare-connection system. Installation by a licensed HVAC professional is required to maintain the warranty.
Is the line set included, and if not, what size do I need to buy?
The refrigerant line set is not included. Exact line set diameter is [NEEDS VERIFICATION] — confirm sizing with the installation manual before purchasing line set separately.
Will the ceiling cassette fit between standard 16-inch on-center joists?
This is a traditional 4-way ceiling cassette, which is designed for a drop-ceiling grid rather than fitting directly between standard 16-inch on-center joist bays. Confirm cassette frame dimensions against your ceiling layout before ordering.
Does this system work in cold climates (low-ambient heating)?
Manufacturer data provided does not include a published low-ambient heating operating range for this model, so this is [NEEDS VERIFICATION].
Compliance & Warranty
Installation by a licensed HVAC professional is required to maintain warranty. Refrigerant handling on this system requires EPA Section 608 certification. Full warranty terms, manuals, and the AHRI certificate for the ASLCI4H4S09/ASLEC4H4S09 pairing are available in the "Resources (System Manuals and Warranty)" Tab above on this page.
